The molecules of Li₂O that would produce if you used up 6 atoms of Li(s) is 3.

<h3>What is Lithiumdioxide?</h3>

It is an unstable inorganic and radical compound, used in the manufacture of glass and ceramic.

The balanced equation

\rm 6 Li(s) + O_2(g) \rightarrow 3 Li_2O(s)

If the atoms of lithium moves up to 6 the lithium oxide molecules will be 3, as you can see in the equation.

Thus, the molecules of Li will be 3.

A. In the complete reaction of 22.99 g of sodium
fenix001 [56]

Answer : 58.44 g

<h3>Further explanation</h3>

The reaction

\tt Na+Cl\Rightarrow NaCl

mole ratio :

Na : Cl : NaCl = 1 : 1 : 1

Molar mass of Na : 22,989769 g/mol = 22.99 g/mol

Molar mass of Cl : 35,453 g/mol= 35.45 g/mol

Molar mass of NaCl : 58,44 g/mol

Let's check the mol for reactant (Na and Cl) and product(NaCl)

  • mol of Na :

\tt mol=\dfrac{22.99}{22.99}=1

  • mol of Cl :

\tt mol=\dfrac{35.45}{35.45}=1

Then the reactants are completed reacting because it matches the mole ratio, which is 1: 1

so that the mole of the product can be determined from the mol Na or Cl, which is 1

  • mass of NaCl :

\tt =\dfrac{mol~NaCl}{mol~Na}\times MW~NaCl\\\\=\dfrac{1}{1}\times 58.44\\\\=\boxed{\bold{58.44~g}}

For the reaction 2h2+o2&gt;h20, how many grams of water are produced from 70 grams of hydrogen
KonstantinChe [14]

630g

Explanation:

firstly the equation has to be balanced. 2H2+o2>2H2o.

finding the mole of hydrogen?

mole = 70/2 which is equal to 35 mole of hydrogen.

35 mole of hydrogen is equal to the mole of water.

finding the mass of water=?

35=mass/18

mass= 35*18=630g of water
